The Lowdown
Righto, Rusty here again. Let's talk inches, feet, and miles per hour for the same stretch at Jaconé.
The first couple of days are a total dud. Wednesday the 2nd is all onshore crud and weak, jumbled-up swell. Save your energy. Then, from Thursday the 3rd, the ocean wakes up, and we've got a couple of sessions worth paddling for.
The clear standout is Thursday the 3rd. You're looking at a clean 7ft south swell with a solid 11-second period, and a sweet offshore breeze out of the ENE. The energy is through the roof at 1091. For any intermediate surfer, this is prime time. Good push but not so big you need to be a charger. Just know that on a day like this, you won't be the only one in the water. In the afternoon, it drops to 6ft from the south as the wind shifts east, making it a little less clean.
Looking further ahead, Monday the 14th is another one for the diary. A long-period groundswell (13 seconds) from the SSW wraps in at about 4ft, but with a massive energy reading of 1112. A light cross-offshore ESE breeze will have the surface glassy and smooth. That long period will give the waves that extra grunt and shape, though it might make things a little straight on the beach break. For experienced surfers chasing quality, this is a top-tier morning.
The second half of the run stays active. From Tuesday the 15th, we get a good run of SSE swells. The morning of the 15th has clean 5ft surf under a light offshore from the NE (energy at 679), and the 16th sees it pump up to 7ft from the SSE (energy at 1117), though with a cross-shore wind that could put a bit of texture on the faces.
We start with a dead patch. No surf worth mentioning from Wednesday the 2nd until the morning of Thursday the 3rd, so just over a day of flat water.
That's the picture from where I'm standing. Keep your eyes peeled and your wax warm. Rusty, out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
